Application June 14, 1937, serial Nt.. 148,203`

3 claim (or 14o- 12 This invention relates to'a Wire tightener and twister and has for an object to provide a novel tool adapted to readily receive the ends of binding wires andproduce a strong even twist, and at the same time tension the wire about the concrete form, box, bale, bundle, package, or the like.

A further object is to provide a device of this character which will be formed of a few strong simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully describedand claimed, it being understood that various modiiications may be resorted to within the scope of the appended claims without departing from the spirit or sacricing any of the advantages of the invention. l

In .the accompanying drawing forming part of this specification, y

Figure 1 is a longitudinal sectional view ot a wire tightener and twister constructed in accordance with the invention.

Figure 2 is a side elevation of the wire tightener and twister with parts broken away.

Figure 3 is a front end elevation of the tool.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, II) designates a cylindrical body provided with internal screw threads II at its rear end. A cylindrical nose piece I2 is screw threadedly engaged in the front end 0f the body and is provided with a substantially conical point I3 adapted to be placed against the concrete form I6, for example, which is to be tied by binder Wire I5. The nose piece I2 is provided with a small opening I6 to permit insertion of a tool for screwing the nose piece into the body.

The body is provided at its front end portion with pairs of spaced guide lugs I1 and I8, respectively, on diametricallyopposite sides of the body, the lugs of each pair being turned oppositely to each other, as best shown in Figure 2. 'I'he lugs on each side engage and hold a respective end portion of the 'binder wire so that when the body is rotated axially, a twist I9 will be made in the wire after the wire is tensioned `by operation of the tool as will presently be described.

The body Ill is provided rearwardly of said lugs with longitudinally extending guide tubes 20. Rods 2I are slidably mounted in the guide tubes and are' connected together outside of the rear end of the body by a bearing 22. The rods are provided at their rear endsby studs 23 Vabout which are wrapped the ends of the wire to be stretched and twisted. 1

A jack screw 2| is mounted in the body and is provided with a cylindrical shank 25 which loosely ilts in the bearing 22 and is provided terminally with wrench faces 26 which are adapted to receive a conventional brace. The jack screw engages the threads lI at the rear end of the body, and is a left hand screw adapted to tighten the wire to proper tension around the form I4 before the twisting operation. A collar 21 is mounted on the shank at the rear end of the jack screw and contacts with the front side of the bearing 22 and a collar 28 is secured to the shank by a set screw 29 and contacts with the rear side of the bearing, to establish a swivel connection between the jack screw and the bearing. When the jack screw is rotated in a direction to be backed out of the tubular body the collar 21 carries the bearing 22 rearwardly. The studs 23 move as a unit rearwardly with the bearing and tighten the Wire, the guide rods 2| sliding rearwardly in the guide tubes 20 during this operation.

The jack screw is provided with a longitudinal groove 30, best shown in Figure 2, to receive the lip 3I of a latch 32 which is pivoted between hinge ears 33 on the body I0, as shown at 34. 'I'he latch isprovided with a handle 35. A spring y 36 is xed at one end to the body by a screw 31 and `bears with its free end against the latch 32 to normally hold the lip 3| lodged in the groove of the jack screw.

During tensioning of the wire as above described, the latch is manually hel-d out of the groove of the jack screw. When it is desired to form a twist in the wire the latch is released and the lip 3| enters the groove 30 and locks the body to rotate asa unit with the jack screw.

Since the operation of the device has been described as the description of the parts progressed it is thought that the invention will be fully understood without further explanation.

What is claimed is:

1. A wire tightener and twister comprising a tubular body provided internally at the rear end with screw threads, a nose piece engaged in lthe front end of the body, guide lugs projecting laterally from the front end of thebody, guide rods slidably mounted on the body to move toward and away from the guide lugs, a member connecting the rear ends of the guide rods, means for securing the ends of binding wire to said guide rods, a jack screw in the body engaging said internal threads of the body, a stem for the the front end of said body, wire engaging guide lugs projecting laterally from the front end of the body, guide tubes on the body rearwardly of said lugs, rods slidably mounted in the guide tubes, a bearing connecting the rods at their rear ends, studs on the rear ends of the rods adapted to engage the ends of the wire to be4 stretched and twisted, a jack screw having a shank swivelly mounted in said bearings, the jack l screw engaging said threads inthe rear of'the body, there being, a longitudinal groove -iormed in the jack screw, and a locking device carriedv by the body and releasably secured in' said groove. n

3. A wire tightener and twister comprising a cylindrical body provided internally at the rear end with screw threads, a nose piece threadedly engaged in the front end of the body, guidelugs extending laterally from the front end of the body,r guide tubes on the body disposed rear- Wardly of said lugs, rods slidably mounted in the guide tubes, a' bearing connecting the rods at their rear ends, studs on the rods about which may be wrapped the ends of the Wire to be stretched and twisted, a jack screw inthe body engagingsaid internal threads of the body and having a shank swivelly -mounted in said bearingfa stop shoulderformed on the shank of the jack screw and contacting with the front side of said bearing, acollar secured to the shank and contacting with the rear side of said bearing, there beinga longitudinal groove in the jack screw, and a pivotspring pressed latch carried by the body and normally engaged in said groove to hold the jack screw against rotation with relation to the body. f
